SPRING-SETTING MACHINE` SPECIFICATION forming part of Letters Patent No. 285,235, dated September 1,8, 1883.

`Aplnlication filed May 5, 18th. (Xo model.) i

To a/ZZ whom it may concern:

. Be it known that l, JOHN CREAGAN, of Cleveland, Cuyahoga county, and State of Ohio, have invented a new and useful lmprovement in Spring Setting Machines, of which the following is a full, clear, and exact description.

My improvements relate to machines of the class shown in the Letters Patent No. 258,382, granted to Creagan and Tyler, May 23, 1882; and the present invention consists in means for holding and adjusting the bars or formers, and in certain other features of construction, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar letters of reference indicate corresponding parts in both figures.

Figure l is a plan view of the machine, and section of the same on the line w Fig. l.

lnthe general construction the machine is the same as shown in the Letters Patent aforesaid.

A is the frame, in which is a sliding carriage composed of end bars, a a, connected by a plate, b, upon which the bars or formers cc are clamped by a top bar, F. d d are the formers, clamped upon a fixed plate, e, by plates f and screws g, each plate f taking upon two of the stationary formers d, for holding the same in place` as adjusted.V Upon the bars or formers c are rubber blocks or buffers h, which are held np to place against the bars c by metal ,blocks i, each block taking against two of the formers, and the blocks t' are attached by knuckle-j oints to the ends of adjusting screws It, which are tapped through a plate, l, that is iixed to the .end bars, a. This construction allows of the adjustment of the bars or i'ormers c d to the form required to be given to the spring, and the buffers h will give way to any slight inequality in the adjustment of the bars. The

' pulleys, p p,

screw, m, and on the end of the screw is a gear-wheel, 01 meshing with a pinion, o, on a counter shaft, which also carries two loose and a fast pulley, q, for the driving-belts r r. s is the belt-shifting rod, connected by a link, i", to the lever s', and the lever is connected to a slide-rod, t, that is tted in suitable guides, one on the frame A and the other,t, 'upon the sliding carriage. Upon the rod t are collars u u.

In the operation of the machine, the bars or formers c d being set to givle the required curve to the spring and the carriage drawn back, the spring is put in place and the rod t then moved to shift the driving-belt upon the fast pulley q, for turning the screw in the direction to force the carriage inward, the other belt being at the same time moved upon one of the loose pulleys. In the forward movement of the carriage, when the spring has been com pressed between the formers, the guide t comes in contact with one of the collarsu upon the slide-rod t, thereby causing the movement of the rod and of the lever s', and shifting the belts r, so that the belt for turning the screw in the opposite direction is carried upon the fast pulley and the other one upon one of the loose pulleys. The Vcarriage is thus brought back until the guide t', acting upon the-other` moves the slide-rod t to the outward and the carriage moves forward, the

collar u, position,

spring having been in the meanwhile removed and another one inserted.

Having thus described my invention, l claim as new and desire to secure by Letters Patent- The combinati-on, with the stationary plate e and formers d. of the clamping-screws g and plates f, substantially as described.
